Conservation of a C-terminal threonine in HA1 of influenza A.

open access: yes, 2015
(A) Alignment of the C-terminus of HA1 and the N-terminus of HA2 for subtypes of influenza A virus. The highly conserved Thr is shown in red. Black letters are amino acids at the C-terminus of HA1.

Enhanced humoural and cellular immune responses to influenza H7N9 antigen HA1–2 fused with flagellin in chickens

open access: yes, 2017
Background Sudden increases in the number of human A (H7N9) cases reported during December and January have been observed in previous years. Most reported infection cases are due to prior exposure to live poultry or potentially contaminated environments.

Measurement of IgG1 and IgG2a antibody titers by ELISA in HA1-Fc- and HA1-Fdc-vaccianted mouse sera.

open access: yes, 2013
PBS was used as the negative control. Ability of IgG1 (A) and IgG2a (B) antibodies binds to the HA1 protein was detected using sera from 10 days post-last vaccination.

Immunological study of HA1 domain of hemagglutinin of influenza H5N1 virus

open access: yes, 2020
a b s t r a c t The neutralization titer of a hemagglutinin (HA)-specific neutralizing antibody against new isolates reflect both the antigenic drift and the conformation status of HA protein in these new influenza viruses. Since most antigenic sites are

An inter-monomer interaction between the HA residues HA1-21 and HA2-47 determines the threshold pH for fusion.

open access: yes, 2014
(A) The Cal/09 HA trimer structure (PDB file: 3LZG) was analyzed using Py-Mol modeling software. The six amino acid differences between the Cal/09 and Bris/10 HA proteins are highlighted in orange. The conserved amino acid HA1-21 is highlighted in green.
